Nursing Tips: Needle Sizes & Gauges

Needles arent the only sign of heroin injection. Heroin needles will likely be attached, or close in proximity to, a syringe or other form of applicator.

Injecting drug users may possess supplies, also known as the works, for sanitizing needles, dressing wounds, or tying off the arm for injection.

How Do You Know What Size Insulin Syringe To Use

Insulin syringes come in multiple sizes with different needle length options.

The correct size depends on your insulin dose and your comfort level with the needle size. Its important to choose the correct size to give yourself the full dose of insulin in one shot and to avoid errors in dosing from using the wrong syringe.

You may need multiple syringes if you give different doses per day. For example, 35 units in the morning and 10 units at night means you need a 0.3-mL syringe and a 0.5-mL syringe for each dose.

Syringes also allow more flexibility if doses need to be adjusted daily based on your blood sugar levels.

If your dose is close to the maximum capacity of the syringe, you may want to go up a size to avoid problems handling the syringe.

How To Choose The Right Insulin Pen Needle Or Syringe

If you live with insulin-dependent diabetes and manage your blood sugars with an insulin pen or syringe, youre most likely taking 2 or more insulin shots a day.

Thats a minimum of 730 times a year that youre piercing your skin with a needle to do an injection.

I do a lot more than 2 injections a day. Im closer to 7 doses a day, which isnt unusual for people living with diabetes. Thats 2,555 injections a year!

I dont mind and it doesnt hurt. But one of the main reasons it doesnt hurt is that I use the right needle, the right injection technique, and I change my needles frequently.

In this article, youll learn how to choose the needle or syringe size thats right for you to minimize pain, avoid scar tissue buildup, and ensure that a full dose is received every time you inject.

Factors Affecting Pain From Needle Insertion

To mitigate pain from hypodermic injections, the effect of needle geometry on pain has been investigated. Needle gauge has been shown to significantly affect the frequency of pain during needle insertion into the skin of human subjects. For example, insertion of a 27- or 28-gauge needle had an approximately 50% chance of being reported as painful, which was significantly greater than insertion of a 31-gauge needle , which had a 39% chance of causing pain. The likelihood of bleeding was also observed to decrease with decreasing needle diameter. Increasing needle length is also expected to increase pain, although to our knowledge the literature does not contain formal studies specifically demonstrating this effect.

In addition, the mechanics of needle insertion has been found to significantly affect pain. Both the force and the mechanical workload of hypodermic needle insertion have been found to positively correlate with the frequency of pain., Thus, needle tip sharpness and other factors, such as lubrication, which can reduce the force of insertion and mechanical workload, are important parameters that can be optimized to reduce pain from needle insertions.

How Do I Dispose Of Syringes And Needles Safely

The easiest and safest way to dispose of syringes and needles is a two-step process. First, purchase a needle and sharps disposal container, and make sure that you put your syringes and needles in there when youre finished with them. They can remain in the sharps container safely for weeks or even months. After its full, dispose of the entire container according to your county or citys guidelines. Needles and syringes should never be thrown out, recycled, or left lying around.

Bmi And Skin Thickness

Needle lengths for subcutaneous injections started out as long as 16 mm in 1985, and 12.7-mm needles were introduced in the early 1990s. Over time, with growing evidence of longer needles increasing risks for intramuscular injections and improved technology, shorter needles of 4, 5, 6, and 8 mm have been developed.

When evaluating skin thickness in 388 patients with BMIs varying from 19.4 to 64.5 kg/m2, Gibney et al. found that a 10-kg/m2 difference accounted for a 4-mm difference in subcutaneous tissue thickness. The average subcutaneous thickness ranged from 10.35 mm to 15.45 mm across all injection sites. This study concluded that 1) the thickness does not vary much between under-, normal-, or overweight individuals and that 2) BMI differences do not cause much variation in the level of skin thickness. The BMI differences were statistically significant but did not make a clinical impact . The skin thickness averages were 1.92.4 mm across several different injection sites , as well as across several BMI levels. With the upper end of skin thickness falling at 2.4 mm, it is logical to assume that a 4-mm needle would be effective in all patients. Therefore, the study further concluded that 4-mm needles would be able to successfully deliver insulin in most adult patients.

Bd Insulin Syringe With Bd Ultra

Choose the syringe that makes a difference they can feel The BD insulin syringe with the BD Ultra-Fine 6mm needle features our shortest insulin syringe needle, at 53% shorter than the 12.7-mm needle. This length is supported by the latest recommendations published in Mayo Clinic Proceedings that advocate using the shortest needle first-line for all patient categories.1* In fact, in a 2010 study, 80% of patients preferred shorter needles compared to 8-mm and 12.7-mm needles.2 They also deliver insulin into the subcutaneous tissue, reducing the risk of painful intramuscular injection.3 Testimonial Videos How to Inject With Insulin Syringes VideosContinue reading > >

The smaller the syringe, the easier it is to read the markings and draw up an accurate dose. If your largest dose is close to the syringe’s maximum capacity, you might want to buy the next size up to handle any increases in your dose adjustments. For example, if your dosage is 29 units and you buy a 3/10 cc/mL syringe, you won’t be able to use those syringes if your doctor increases your dosage to 31 units. BD 3/10 cc/mL syringes are available with dosage markings at every half-unit.

What Are The Different Syringe Sizes


A syringe is a plastic or glass cylinder that contains a plunger that goes in one end and typically has a needle attached to the other. The term syringe can refer either to all three components the cylinder, plunder, and needle or just to the cylinder portion. Syringe sizes are indicated in milliliters and can range from 0.25 ml up to 450 ml. They also can be stated in cubic centimeters, where 1 cc is the approximate equivalent of 1 mL. These numbers indicate the volume of liquid that the cylinder is able to hold.

When referring to the unit as a whole, syringe sizes also might be given for the needle portion of the syringe because the size of the cylinder is often used to determine the size of the needle that will be attached to it. The needles themselves are categorized by length as well as the needles gauge, indicating the overall thickness of the needle. Contrary to most measurement systems, the higher the needles gauge, the smaller it actually is.

There are other types of syringes, however, that do not include a needle as a component of their design. These include oral syringes, which most often are used to dispense liquids to babies or small children. Oral syringes differ from standard syringes only because of their tapered tip in place of a needle, so the same sizes are used to indicate how much liquid can be contained within the cylinder.

How To Dispose Of Pen Needles

These needles may be tiny, but theyre still considered hazardous medical waste and should be disposed of in official sharps containers. Local communities and states have varying disposal rules, sometimes allowing you to include these in sharps containers to put out for recycling just like insulin syringes.

You can read our DiabetesMine guide to disposing of used diabetes supplies, which includes these important tips:

  • Never throw loose pen needles into the trash or directly into a recycling container.
  • Put the used pen needle into a home sharps container, or something similar that follows your local rules on properly disposing of used sharps objects.
  • You can clip the needle with a special needle-clipping device, such as the BD Safe-Clip. Those can be picked up your local pharmacy or ordered online.
  • If you inject someone else or dispose of their pen needle, use extreme caution to avoid getting pricked, which can transmit infections.

What Does Gauge Of Needle Mean

Also to know is, which is bigger 18 or 20 gauge needle?

18 Gauge: This size allows you to do most tasks that the 16 gauge can, but it large and more painful to the patient. 20 Gauge: You may be able to push blood* through this size if you can’t use an 18 gauge, but always check your employer’s protocol. This size is better for patients with smaller veins.

Also, how do needle gauge sizes work? Hypodermic needles are available in a wide variety of outer diameters described by gauge numbers. Smaller gauge numbers indicate larger outer diameters. Inner diameter depends on both gauge and wall thickness.

Also question is, what is a 16 gauge needle used for?

21-gauge needles are most commonly used for drawing blood for testing purposes, and 16– or 17-gauge needles are most commonly used for blood donation, as the resulting lower pressure is less harmful to red blood cells .

For intramuscular injections, the usual route is the deltoid muscle. The ideal needle gauge ranges between 22 and 25 and a length of 1 to 1 ½ inch. However, the length of the needle should be in accordance with the patients weight.

The heavier the patient is the longer the needle should be. Aside from the deltoid muscle, intramuscular injections can also be done in the anterolateral thigh muscle.

Heroin Needle: Identifying A Heroin Syringe

Possessing needles and syringes can be a sign of heroin use. Injection is the most common way people use heroin. Injecting heroin can cause a range of acute and long-term health consequences that may require medical and behavioral health treatment.

Heroin is a highly addictive drug that can cause a fast but short-lived high when injected into the veins , muscles , or under the skin .

Although heroin can also be snorted or smoked, shooting heroin is the most common way that heroin is used, especially among people aged 35 and older.

Drug paraphernalia associated with heroin injection includes:

Identifying drug paraphernalia in the possession of a family member or loved one can be one of the first warning signs of heroin addiction. Addiction to heroin can be treated in an inpatient or outpatient substance abuse program.

Gauges And Needle Length

The measurements of needles relate to how long the needle is. When a needles measurement is 31G, the G refers to the gauge of the needle. This donates the thickness, size, or capacity.

The gauge and needle length will contribute to perceptions of pain when injecting.

The longer the needle is, the harder it is to pressurise the insulin through so it needs a bigger hole down the middle.

What To Keep In Mind When Choosing A Syringe


When choosing a syringe, you have to consider the size. Make sure the size of the syringe matches the volume of the drugs to be given as well as the desired pressure flow. If you are going to give large volumes of drugs, then you would need a large syringe. The same thing goes for low-pressure flow.

Syringe Tips There are many types of syringe tips and these are the following:

  • Luer Lock Tip When it comes to syringe tip, one of the common options is the Luer Lock Tip. It secures the needle in place by twisting it on.
  • Slip tip The needle is placed onto a slip tip syringe without having the need to twist it. A catheter slip tip is used with medical tubings such as feeding tubes and catheters.
  • Eccentric Tips It is the perfect syringe tip if you are going to introduce drugs parallel to the patients skin such as a vein near the skin surface.
  • Catheter syringe tip The tip is tapered to enable the tubing to slip onto the tip. It is primarily used for irrigation.

Needles They have a hub at one end that attached to the syringe. Needles come in different lengths and are measured in inches. They also vary in gauge sizes. thin needles have high gauge sizes. The tip of the needle has a bevel/slope to allow the needle to easily pass through the tissues. When it comes to choosing a needle for your syringe, there are a few things to keep in mind. They are the following:

Tuberculin Versus Insulin Syringes

32 gauge insulin needles.mp4

Patient was tested for allergies in a primary care doctor’s office. He will be getting allergy shots for cat, mold and dust allergies. The technician who is managing the program for the doctor ordered insulin syringes for the allergy shots instead of tb syringes. She claimed that 10 Units on an insuling syringe is equivalent to 0.1 cc on a tb syringe. Is this common practice to use insulin syringes for allergy shots? She said they are cheaper than tb syringes. Thank you Thank you for your inquiry. There are differences between tuberculin and insulin syringes. The two links copied below will take you to websites that discuss these differences. This does not preclude insulin syringes from being used to administer allergy injections, but one has to be very careful about the conversion units involved. In addition, syringes specially designed to administer allergy injections are also available for purchase at suppliers. These are designed specifically for that task. It’s All in the Syringe What is the difference between a tuberculin syringe and an insulin syringe? Thank you again for your inquiry and we hope this response is helpful to you.

What About Leakage Concerns Related To Shorter Needles

Some people have raised the concern that short needles will lead to leakage or that they arent suitable for people with larger bodies.

That concern has been debunked and research has shown that shorter needles work for most body types, with no additional leakage.

But if you feel more comfortable using a longer needle, then you should absolutely do that.

What To Keep In Mind

  • For intradermal injections, the recommended needle gauge is 26 to 28.
  • For intramuscular injections, the recommended needle gauge ranges between 26 and 30.
  • For subcutaneous injections, the recommended needle gauge ranges between 19 and 27.
  • The needle is small if the gauge and number are high.
  • When introducing viscous/thick drugs, you need to use a big and wide needle.
  • Lower gauge needles are big and strong thereby preventing the possibility of bending or breaking.
  • Higher gauge numbers cause less pain and discomfort.
